T0 @ZZ whom, t 71mg/ concern:

Be it known that I, CHRISTIAN J. Boos, a citizen of the United States, residing at .I ackson, in the county of Jackson and State of f Michigan, have invented certain new and usel ful Improvements in Brick-Making Machines, of which the following is a specification.

This invention relates to brick-m aking inachines.

One object of the invention is to provide a brick-machine provided with a swinging mold having means designed to hold the finished bricks against accidental displacement with respect to the pallet-board when the mold is shifted from over the bricks and pallet-board.

Another object is to provide a brick-machine having a face-plate designed to hold the bricks against accidental displacement when the mold is shifted out of contact with the completed bricks.

Another object resides in the provision of a brick-machine embodying such characteristics that its mold may be readily shifted forwardly and backwardly upon a horizontal axis.

Another object is to provide a comparatively simple, inexpensive, durable, and efflcient machine of the nature stated.

Another object is to provide a machine of the nature stated embodying such characteristics that the mold may be readily and properly positioned to receive the plastic material and then swung to an inverted position to permit of the ready discharge of the molded material. v

A still further object resides in the provision of a brick-machine so constructed and arranged that the mold' thereof may be readily and quickly dropped from one position to another and then turned over into an inverted position to permit of the ready removal of the bricks therefrom.

It is s till further designed to provide a brick- :machine embodying such characteristics that the mold maybe dropped in a vertical direction from one position to another and then turned over vertically to an inverted position, there being a face-plate so constructed and arranged with respect to the mold and the bricks to hold the latter against accidental displacement relative to the pallet-board when the mold is given a reverse turn from over the bricks to be positioned for repetition of the aforesaid movements.

In the drawings, Figure 1 is a perspective y view of the machine ready for operation. Fig. 2 is a similar view illustrating the mold dropped from its normal position to an inclined plane. Fig. 3 is another similar view illustrating the mold in its inverted position. Fig. 4 is a similar view of the mold when moved from over the bricks to permit the removal of the pressed or molded bricks. Fig. 5 is a transverse sectional view on the line a. av of Fig. 1, illustrating the inverted position of the mold in dotted lines. Fig. 6 is a transverse sectional view on the line l) I) of F ig. 4. Fig. 7 is a detail view of one of the clampingelements. Fig. S is a detail view of the other clamping element. u

In carrying out the present invention the mold of the machine is indicated by the numeral 1 and is mounted for operation within a suitable frame consisting of ground-sills 2 and 3, upon which are secured in any suitable manner the pairs of supporting-legs 4 and 5, respectively, the front legs of each pair being connected intermediate their ends by a cross-piece 6, upon whichlatter and connecting the respective pairs of supporting-legs are suitable arms 7 and S. It will thus be seen that since the cross-piece 6 is disposed at a right angle to the arms 7 and 8 and the latter resting upon the former the arms thereby and by their connection with the supportinglegs are firmly supported for the purpose for which they are designed and as will be apparent from a further reading of this specification. The supporting-legs above the arms are connected by the side members 9 and 10 and the back member 11, between which and intermediate the upper and lower edges thereof is arranged a shelf 12 designed for the reception and support of the brick-making material, all of which is clearly shown in the accompanying drawings.

Side rails 13 and 14 are connected to the in- IOC ner faces of the respective arms 7 and 8 and above the upper faces of the arms, each being provided in its upper face with a forward andv a rearward socket, as indicated by the characters and 16, the respective sockets of the opposite arms being in alinement. Each rail 13 and 14 is provided with a depending perforated ear 17, which are designed to aline and in which is journaled a horizontally-disposed shaft 18, arranged beneath the plane of the under faces of the aforesaid arms 7 and 8. Mounted upon and for rotation with this said shaft 18 are two clampinglevers 19, provided each with an ear 19 adapted to coperate with the lugs 20, one of the latter being disposed upon the adjacent ear 17 of the rails 13 and 14 for a purpose presently understood. A screw or other suitable element 19'r1 is passed through each lug 20 for coperation with the corresponding ear 19.

The mold in the present instance comprises sides 21 and 22, each provided with an ear 24. Each side is also provided with a slot 25, adjacent each of which latter is arranged a pair of ears 26, designed to receive pivotally between them a cam or other lever 27, designed to enter through the corresponding slot 25 and secure the pallet-board28 in proper position against accidental displacement with respect to the mold-box. The back of the mold-box is in the form of a facing-plate 29, provided with a series of vertical slots 30 for the reception therein of the division-plates 31 of themold. The upper edge of the back plate 29 is directed outwardly from the mold for engagement with the aforesaid bench or shelf 12 to prevent it from swinging outwardly upon its pivot-rod 32, the latter being disposed in the alining ears 24 of the respective sides of the mold. The front of the mold is formed by the separators or boxes 33, between which the corresponding ends of the corresponding division members or plates 31 are fitted, there being suitable bolts 34 andA 35 passed through the sides 21 and 22, the

separators 33, and alsothe division-plates 31.

The bottom of the mold is strengthened by means of a metal or other suitable strip 36, as shown.

While the back plate of the mold serves as a facing-plate, the inner faces of the aforesaid boxes or separators do not form the front facing members. On the other hand, I provide a swinging arm 37, which is preferably of an inverted-T formation in section and whose base portion 38 is secured, by means of a series of suitable fastenings 39, to the flanged edge 40 of a series of combined front and bottom facing members and means for holding the bricks against displacement with respect to the aforesaid pallet-board. These combined members are of a Z form, as shown, the portions 41 being secured to the aforesaid arm 37 the portions 42 serving as the front facing members and the portions 43v serving as the bottom facing members, the free ends of the latter resting upon cleats or shoulders 44 when lowered into'the mold. The first-named portions of the Z-shaped members are out of contact with the spacing separators or boxes, as clearly shown in Fig. 5, The arm 37 is provided with appropriate slots 45 on its front portion to prevent interference with the tops of the division-plates during revolution of the mold. This arm 37 also has a nger 47 at each end for a purpose presently explained.

Connecting the rails 13 and 14 is a palletboard support-48, provided with the adjustable pallet-board connections 49, and it is between this support 48 and the shelf 12 that the mold is positioned. For instance, ,each side member 21 and 22 of the mold has a trunnion or fulcrum 50 for engagement in the alining rear sockets 16 of the rails 13 and 14, and these trunnions or fulcrums aid the slotted guide-plates 51 and 52 to support the mold-box in a horizontal position, the lower ends of the slots of said plates terminating at an angle to the elongated portion thereof to form a shoulder 53 for engagement upon the corresponding projection 54 of the side rails 13 and 14. These guide-plates are provided with trunnions or fulcrums 55 at their upper ends, which are perforated, whereby the guide-plates may have pivotal movement upon the corresponding end of the pivot-bolt 56, upon which the aforesaid swinging arm 37 is mounted. that the shoulders of the guide-plates may be disengaged from the projections 54 of the rails 13 and 14 to permit dropping of the front end of the mold, so that the fulcrums 55, which are rounded, may engage in the front alining sockets 15 of said rails and dispose the mold-box upon a forward incline, as shown in Fig. 2.

The operation of my invention is as follows: Regardless of the character of frame in which the mold is mounted, it will be stated that the concrete or plastic substance is placed in the mold when the same is in the position shown in Fig. 1. As illustrated, the shelf 12 prevents outward movement of the back facing-plate and is arranged, preferably, upon a level with the-upper edge of the back facing-plate. The material is taken from said shelf and placed within the mold, after which and while the mold is in the position shown in Fig. 1 the pallet-board 28 is placed in proper position and clamped by means of the clamping elements 27. The guide-plates '51 and 52 are swung slightly, causing their shoulders to become disengaged from the projections 54 of the rails 13 and 14 when the box fallsto the position shown in Fig. 2. In this position the trunnions or fulcrums 55 are disposed in the forward alining sockets It will thus be understood IIO of the rails 13 and 14. The mold-box is then revolved or swung upon bolt 56 into the position shown in Fig. 3, the ends of the fingers 47 of the swinging arm 37 being clamped between the lugs 20 of the depending ears of the side rails 13 and 14 and the ears of the clamping-levers. The levers for holding the pallet-board are then manipulated to permit of the loosening of the latter. A lever l) is then inserted in the socket c of the back plate, and the lever 19 is raised until the fingers 47 of the arm 37 are held firmly against the lugs on the inner faces of the depending ears of the rails 13 and 14, and then the moldbox, with the exception of the pallet-board and the series of combined double face-plates and brick-holding elements, is rotated or swung backwardly, as shown in Fig. 4. It will thus be seen that the pallet-board, with the finished bricks thereupon, is left upon the pallet-board support and that asthe moldboX is moved backwardly to leave the palletboard and bricks in the position stated the double facing members serve to prevent displacement of the bricks with respect to the mold-box. After this operation downward pressure upon the lever 19 will cause the double facing members to move away from the bricks to a slight degree, so that the pallet-board and bricks may be removed from the pallet-board support. Then the double facing members and brick-holding means may be rotated or shifted backward upon the pivot 56 until it is possible to lift it and the mold-box to a horizontal position for repetition of the operations described. It might be remarked that the arms (L of the fulcrums 55 maybe used to disengage the guideplates 51 from the projections 54 and also to swing the mold.

From the foregoing it will be seen that the mold-box may be droppedv verticallyT upon a forward incline and then turned completely over into inverted position. It will also be seen that the mold may be turned from over the bricks with elements of the same, serving to prevent accidental displacement of the bricks with respect to the pallet-board support or the pallet-board itself and afterward moved into engagement for coperation with the mold-box. In other words, it will be seen that when the mold-box has been thrown to its inverted position parts thereof may be taken from over the bricks, while a part or parts remain adjacent the bricks to prevent accidental dislodgment of the latter. It will also be understood that when the lever b is used to throw the mold back the operation causes a slight swinging of the back plate to prompt the latter to clear the corresponding faces and edges of the bricks, thereby preventing chipping or breaking of the latter.
